Answer:
B. 144
Step-by-step explanation:
To find the algebraic expression, simply break the sentence into fragments.
Three times a number - 3x
5 less than three times a number is 5 - 3x.
This equals to 10.
5 - 3x = 10
-3x = 5
X = -5/3.
I believe this would be the solution.
j = # of jars
b = # of buckets
y = total # of rocks
2j + 3b = y (2 rocks per jar, 3 rocks per bucket)
Because Joy has 3 jars you can plug 3 in for "j", and because she has 4 buckets you can plug in 4 for "b"
2(3) + 3(4) = y
6 + 12 = y
18 = y
So you need 46 which means that you can’t have less than 46 otherwise you won’t have enough
46/10 = 4 packs + 6 more plates
If you only buy 4 packs you will have 40 plates but you need 46 so buy an extra pack.
So you will need to buy 5 packs of plates.
I hope this helps :)
